Cyanide Chemistry &Gold Extraction

In the chlorination process the gold requires only free chlorine and water for its solution, as the chloride of gold is soluble in water, but in the cyanide process there are required, first free cyanogen to form the cyanide of gold, and then free cyanide of potassium to form the soluble double cyanide.

This is a very simple process where they can burn off the mercury to get a gold nugget for sale. Cyanide is much cleaner compared to those artisanal methods. It is more complex to use and collecting the gold requires several steps and equipment. Unlike mercury, cyanide breaks down to harmless compounds in the environment.

Potassium Cyanide Assignment Point

Potassium cyanide is a white poisonous granular soluble solid substance used in photography and in extracting gold from its ores. It is highly toxic. The moist solid emits small amounts of hydrogen cyanide due to hydrolysis, which smells like bitter almonds.

Gold cyanidation

Gold cyanidation

Gold cyanidation (also known as the cyanide process or the MacArthurForrest process) is a hydrometallurgical technique for extracting gold from lowgrade ore by converting the gold to a watersoluble coordination complex. It is the most commonly used leaching process for gold extraction.

CN103290232A Method for extracting gold from auriferous

The invention relates to a method for extracting gold through potassium ferricyanide. The method is characterized in that the gold is extracted from the auriferous ores under an alkaline environment at normal temperature and pressure with nontoxic ferricyanide serving as a gold leaching agent and calcium peroxide serving as a leaching adding agentand the method is a completely novel cyanide
